Development of a suitable pragmatic and cost effective biomonitoring method for assessing water pollution in tropical African rivers
(NM-AIST, 2015-09)The needs of tropical African countries to develop their own biomonitoring indices using local macroinvertebrates as opposed to adoption or relying on non-tropical indices in biomonitoring programmes for assessing freshwater ... -
Modelling of energy demand and supply patterns in Tanzania
(2016-04)Energy is an important element in realizing the interrelated socio-economic development of countries. In an attempt to develop long term energy demand and supply patterns that would enable the country meet her growing ... -
Design of controlled release fertilizers on the base of polymeric, nanoclays and nanocomposite excipients
(2016-04)It was hypothesised that agronomically suitable controlled release fertilizers (CRFs) can be prepared using synthetic and/or natural biopolymers and polymer-clay nanocomposite excipients. Literature has focused almost ... -
Theoretical study of structure, vibrational spectra and thermodynamic properties of cluster ions existing in vapours over barium dihalides
(NM-AIST, 2017-12)Computational and theoretical methods were employed to study the structure, vibrational spectra and thermodynamic properties of cluster ions that were detected earlier in saturated vapour over barium dihalides. The equilibrium ... -
Biogas slurry derived mesoporous carbon/metal oxides composites for supercapacitors application
(NM-AIST, 2017-12)With the increasing utilities of intermittent renewable energies, hybrid electric vehicles and portable electronic devices, supercapacitors have been identified as one of the solution for energy storage since they can ... -
Study of crustacean biomass wastes for water defluoridation
(NM-AIST, 2018-09)High levels of fluoride (F-) in community drinking water supply is recognized as one of the major public health problems. Until now no efficient and affordable F- removal technology exists in many regions. This research ... -
Impacts of future climate and landuse changes on surface-groundwater balance in Usangu catchment
(NM-AIST, 2019-02)This study was undertaken to assess the impacts of future climate and land use/cover changes on surface-subsurface water balance in Usangu catchment, located in the Southern highlands of Tanzania. The objectives of the ... -
Optimization of incineration process
(NM-AIST, 2019-02)Municipal solid waste management has become a challenge in many cities in the developing countries due to the poor methods of waste disposal, which increase the risk of the spread of diseases, leach and increase the demand ... -
Potential of Scoria, Pumice, and RHA as Supplementary Cementitious Materials for Reducing Setting Time and Improving Early Strength of Pozzolan Blended Composite Cement
(NM-AIST, 2019-10)Tanzania has huge deposits of scoria (S-N) and pumice (P-N) minerals that can be used as supplementary cementing materials (SCMs) in cement factories to cut down the cost of cement and its pollution effect to the ... -
Mesoporous carbon materials derived from artocarpus heterophyllus for water desalination and defluoridation using capacitive deionization
(NM-AIST, 2020-02)Sustainable clean water for human use can be attained through cost-effective water purification technologies whereby capacitive deionization (CDI) technology is among them. To attain high CDI performance porous carbon ... -
Geological and hydro-geochemical assessment of fluorine around mount Meru, northern Tanzania
(NM-AIST, 2020-03)Areas around Mt. Meru are among the areas in Tanzania where climate change, population growth and high fluoride levels in much of the water sources lower availability of water for domestic ... -
Assessment of groundwater abstraction and hydrogeochemical investigation in Arusha city, northern Tanzania
(NM-AIST, 2020-03)In this work geological and hydrogeochemical data, radioisotopes and stable isotopes, and groundwater hydrographs were used to assess the groundwater abstraction trends and hydrogeochemical characteristics of Arusha ... -
Land use change and temporal water quality dynamics on the slopes of mount Meru
(NM-AIST, 2020-09)This work reports on the results obtained following the study on the land use change and temporal water quality change in rivers of the slopes of Mount Meru in Northern Tanzania between 2015 and 2016. Satellite images ... -
Towards sustainable management of inland waters in Tanzania assessing the ecological integrity of river ecosystems in the upper Pangani river basin (Tanzania)
(KU Leuven, 2020-12)River ecosystems encompass river channels and its floodplains and form a diverse mosaic of habitats upon which countless species of animals and plants depend for survival. They provide a plethora of services for humans ... -
Controlling ammonia and sulfide inhibition during anaerobic digestion of slaughterhouse waste
(NM-AIST, 2021)The performance of experimental batch-reactor loaded with slaughterhouse waste at mesophilic temperature was investigated as well as the inhibition of both ammonia and sulfide in the aqueous phase during phase I of ... -
An eco-friendly tanning method using plant barks and their combination with aluminium sulphate from kaolin for leather industry
(NM-AIST, 2021-02)Chrome tanning has remained the most preferred tanning method worldwide in the leather industry because it produces leather of a high quality with all the desired features. However, environmental concerns of chromium ... -
Strategies to improve anaerobic digestion and environ-economic analysis of municipal solid wastes management options
(NM-AIST, 2021-06)Different strategies have widely been applied for improving the anaerobic digestion of the organic fraction of municipal solid wastes. However, because of the heterogeneous compositions of organic fraction of municipal ... -
